For some reason I am unable to "Thank" people. I click the button and it disappears, but then when I reload the page the button is there again and my count is still 0. This isn't a big deal, but I don't want to appear ungrateful to the nice people who give me advice. Am I missing something?

For a time, I couldn't see anything to do with thanks or the mc points, that was for a week or two pretty shortly after I joined. I thought it just had something to do with the thanks being disabled if the system thinks you're abusing them. I assume that's automated, right?
